Multiple Files Renaming with space - UNIX for Dummies Questions & Answers

nazri76 · #1 (**permalink**) 09-20-2007

Hi,

I need help how to renaming multiple file. The original file look like this;

Test Monday.txt
Test Wednesday.txt
Test July.txt

I have more than hundred file in the directory.

How i want to rename all file to a new file name in one time? The new file maybe the same name e.g. TestMonday.txt OR different file name e.g. Test MondayJuly.txt

You will have to run a loop that goes over all the files in the directory one at a time, because you can only rename one file in one mv command.

If you want to do this, you will have to establish some logic that can translate your current name to your new name. That means that all files will be renamed in a similar manner (removing the spaces in the filename, for instance).

i still can't get it. Maybe i give another example, i have original file as below;

Test Fish#10125#STAR.txt
Test Fish#52134#MOON.txt
Test Fish#32598#CLOUD.txt
Test Fish#66789#STORM.txt

I need to remove the space between "Test Fish" but i want to do one time for all file before i encrypt it.

After i encrypt the file, the file name will become TestFish#10125#STAR_encrypted.txt ... so i need to change back to original file name also in one time for all files.

Does anyone know how to do this or know what ‘functions’ I should use???

With the Z-Shell:

Code:

zsh 4.3.4% touch Test\ Fish#10125#STAR.txt Test\ Fish#52134#MOON.txt Test\ Fish#32598#CLOUD.txt Test\ Fish#66789#STORM.txt
zsh 4.3.4% autoload -U zmv                                                                                                
zsh 4.3.4% zmv  '*' '${f// /}'                                                                                            
zsh 4.3.4% ls
TestFish#10125#STAR.txt  TestFish#32598#CLOUD.txt  TestFish#52134#MOON.txt  TestFish#66789#STORM.txt
zsh 4.3.4% zmv  '*' '$f:r_encrypted.txt'                                                                                 
zsh 4.3.4% ls
TestFish#10125#STAR_encrypted.txt   TestFish#52134#MOON_encrypted.txt
TestFish#32598#CLOUD_encrypted.txt  TestFish#66789#STORM_encrypted.txt
zsh 4.3.4% zmv  '*' '${f//_encrypted/}' 
zsh 4.3.4% ls
TestFish#10125#STAR.txt  TestFish#32598#CLOUD.txt  TestFish#52134#MOON.txt  TestFish#66789#STORM.txt

A simpler way,

Code:

ls Test* | while read file
do
mv "$file" `echo "$file" | sed 's/ //'`
done

Case1: TestFish_done.txt to Test Fish Done.txt,

Code:

#!/bin/ksh
for oldfile in $(find . -name TestFish*)
do
   newfile="$(echo $oldfile | sed 's/Test/Test /g'|sed 's/\_/ /g')"
   mv "$oldfile" "$newfile"
done

Case2: FishOne_done.txt to FishOne.txt

Code:

#!/bin/ksh
for oldfile in $(find . -name FishOne*)
do
   newfile="$(echo $oldfile | sed 's/_done//g')"
   mv "$oldfile" "$newfile"
done
